← ScienceWhich mechanism dictates increased melting point within polymers?
A)Increased Van der Waals forces
B)Decreased side-chain steric hindrance
C)Reduced molecular chain branching✓
D)Enhanced intramolecular vibrations
💡 Explanation
Reduced chain branching allows closer molecular packing, therefore it elevates the necessary thermal energy needed to transition into a liquid phase because stronger intermolecular London dispersion forces overcome thermal jostling. Rather than only intramolecular vibrations causing phase change.
